My mythtv server has one infrared receiver because it comes with the pvr-150 card. My mythfrontend is a different machine that has no infrared receiver.

| July 8, 2007 | Reply

Veritas products have always been confusing. I’m writing here to archive an experience that we had with netbackup and ACSLS (Automated Cartridge System Library Software) in our data center. Essentially, all of the drives in our media library were up as AVR (Automatic Volume Recognition) as opposed to ACS (Automated Cartridge System). This means that …
